The ratio of girls to boys in Liza's classroom is 5 to 4.
How many girls are in her classroom if there is a total of 27 students?

Answers

Answer 1

Hi!

The answer is: 15 girls.

__________________________________________________________

Let

x-----> the number of girls

y-----> the number of boys

we know that

- x+y=27, Which is equation A.

- x/y = 5/4

- isolate the variable y

- y=4/5x, Which is equation B.

- 9/5x=27

- x=5x27/9

- 15 Girls.

Hope this helps!

Solve for x by factoring

There are multiple answers

Answers

Answer:

[tex]x=3,-7[/tex]

Step-by-step explanation:

We can solve for x by using [tex]\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}[/tex]

By applying this on the quadratic equation, we get:

[tex]x=\frac{-4\pm\sqrt{4^{2}+84} }{2}[/tex]

Which simplifies to:

[tex]x=\frac{-4\pm10}{2}[/tex]

[tex]\therefore x=3,-7[/tex]

The cost of a gym membership is $25 per month. There is an initial fee of $40

Answers

Answer:

y = 25x + 40

Step-by-step explanation:

Using the formula, y = mx + b we can find out what this equation would be.

m = the rate of change/slope

b = the y- intercept

25 per month is telling us that this is the rate of change.

Since the $40 is only paid once, you can tell that this is the y intercept.

The equation will look like:

y = 25x + 40

On a graph it would look like:

Let the total cost of a gym membership be y, with the number of months as x.

The total cost would be 40 dollars, the initial fee, plus 25 times the number of months (x).

y = 40 + 25x
